Furnace Repair in Manassas, VA — Book a Visit Today
A furnace that lights, runs a minute and shuts off again is one of the more common heating repair calls we take. We do furnace repair across Manassas on gas and electric equipment, and we start by reading what the control board is telling us rather than guessing at parts. If you smell gas, leave the house first, call 911 or the gas utility from outside, then call us. Otherwise check the thermostat batteries and the filter, since a clogged filter overheats a heat exchanger and trips the limit. Reach out by phone or through the quote form and we will get you scheduled.

My furnace will not turn on at all. What should I do?
Check the thermostat batteries and setting, then look for a tripped breaker, and swap a filthy filter. If none of that brings it back, call us for heating repair. We do not want you opening panels or touching gas or high-voltage parts.
Is it worth repairing an older furnace?
Often yes, if the heat exchanger is sound and the failed part is an ignitor, sensor, motor or board. We tell you what we find and what the repair involves so you can weigh a repair against replacement without pressure from us.
What does a burning smell at first startup mean?
Dust burning off the heat exchanger is common the first cold week and fades within an hour or two. A smell that lingers, smells electrical, or comes with smoke means shut the system off at the thermostat and call us for furnace repair.
Why does my furnace keep shutting off before the house warms up?
Short cycling usually points to a flame sensor coated in residue, a restricted filter, a blocked flue or an overheating limit switch. It is a safety doing its job. Change the filter first, and if it repeats, book a visit.
How soon can you get to my house in Manassas?
Call us and we will give you a real window rather than a guess. During a July heat run or the first hard freeze, same-day slots fill early, so morning calls have the best chance. If you are without cooling or heat, tell us when you call and we will treat it that way. Before we arrive you can check the thermostat batteries and settings, look for a tripped breaker, change a clogged filter and clear leaves or mulch away from the outdoor unit.
How it works
- Step 1
Tell us the symptom
Call or fill in the form and describe what changed. Warm air, short cycling, a smell, water near the indoor unit. Details like that help us load the right parts before we leave.
- Step 2
We diagnose the whole system
We check the thermostat, the indoor unit, the outdoor unit and the ductwork, including runs in crawlspaces where damp air and loose joints quietly cause weak airflow and long run times.
- Step 3
You approve the fix
We explain what failed, what it takes to repair it, and what we would watch next season. Nothing gets replaced without your yes, and we clean up before we leave.

Why homeowners call us
- Humidity is our home groundMuggy summers and damp shoulder seasons drive most of the calls we take. We look at moisture and airflow together, not the cooling number alone, because a clammy house often means a sizing or duct problem.
- Crawlspace ducts get checkedOlder homes across the region run supply ducts through vented crawlspaces. Crushed flex, disconnected boots and soaked insulation show up constantly, and we get under the house to look instead of guessing from the register.
- Heating and cooling bothSame crew for air conditioning repair in July and heating repair in January. We know how your furnace, heat pump and air handler share ducts and a blower, so one visit covers the whole system.
- Plain talk on repair or replaceWhen a repair makes sense, we repair it. When a system is failing in ways that will keep costing you, we say so and explain why, then leave the decision with you and your timeline.
